Create SMB share on datapool

Oct 5, 2023
I'm new to proxmox backup server and wanted to know if its possible to create a simple SMB share for virtual machines on the same network that could be used for e.g. MySQL dumps/backups. I noticed that samba is already preinstalled and I could just create a share under /mnt/datastore/... but then Im not sure if pruning jobs would remove those "manually" created files from the dfatastore.
Should I (at least) create a seperate namespace without any verify/prone jobs or is it safe to have those inside the same datastore as Proxmox VE VM backups?

you should not re-use the directory used as datastore for other purposes, but you can of course do other things on your PBS system as well (using other directories ;)). whether those other things interfere with operations of PBS depend on what exactly you are doing, how beefy your setup is, etc.
As I said it should just serve as a backup target for some services like MySQL or similar (e.g. daily .tar.gz uploads) so performance is definitely not an issue. So I should take a couple of disks out of that datastore and just create a "normal" LV/VG instead of a datastore, right?
you should not re-use the datastore directory for anything else. you can re-use the disks that contain your datastore dir for other things - how exactly that would work depends on your disk/storage setup which you haven't mentioned so far..
I have similar question: I would like to use Proxmox backup server and ZFS/ deduplication features to backup from my windows machines. Should I use Samba? All suggestions and good practices advice is appreciated....

Keep the RAM requirements in mind. ZFS deduplication needs an additional 5 GB RAM per 1TB of data. Because of this ZFS deduplication is rarely used as it is most of the time just not worth it unless you got something like a DB with lots of identical entries or similar well deduplicatable data.
